Sumatra PDF Freeware by Krzysztof Kowalczyk

view all images (4) This small program is able to open and display different popular files and documents, including PDF, different e-book (and comic) formats.

I like that is opening documents very fast. Besides this, allows to rotate page, change view mode to presentation or fullscreen, zoom at any percent.

You can add pages at Favorites in Sumatra PDF's interface, search in document by word, change default layout from Options to continuous, book view and more.
